[PATCH 0/2] swait: add idle to make idle-hacks on kthreads explicit

[Luis R. Rodriguez]

In this proper patch form I've made the non-timeout idle swait void.
I've also integrated Paul's comment / ident changes, and added documentation
as suggested by Boqun.

Let me know if there are issue, otherwise, Paul feel free to take!

Luis R. Rodriguez (2):
  swait: add idle variants which don't contribute to load average
  rcu: use idle versions of swait to make idle-hack clear
